I was wondering how much a used STi/WRX short block costs and where I can find them? I saw someone post on here that you can find them between $700-$900.
Also I have an 04 WRX and I was wondering if the Sti Block will mount right up to my WRX head? And if it does will there be any performance gains since the block is a 2.5l?

I know hondas does cause I had an ls/vtec and different block with different head=more performance. I just don't know if it is the same with subarus.
